You must not change the existing clock indices like this, use indexes that are currently unused for CLK_PPMU* clocks. If you do that the kernel would stop working with existing dtbs. This interface is an ABI, so you can't just rearrange the indices at will like this. -- Regards, Sylwester -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
